(Not an idiot-plot power fantasy. The supporting characters are sensible, there’s plenty of comedy, and you don’t need to play miHoYo games to enjoy it. The story has nothing to do with the games.)
Li Xinghe is a version diver. After refusing to pull for The Herta and the Remembrance characters, he got destroyed by the Banana Band in the 3.1 Apocalyptic Shadow, then dropped dead on the spot in a fit of rage and transmigrated to a parallel world.
As Li Xinghe looked at his fifteen-year-old body and swore to make up for the regrets of his past life, he discovered that this was a high-martial-arts world with a completely different history. Blue Star had connected with the universe over a hundred years ago. Blue Star’s powerhouses could split mountains, part seas, and tear apart the sky and earth, but they were little more than country bumpkins. The stars were filled with countless even stronger beings.
Just as Li Xinghe was feeling emo, the miHoYo System arrived, and he chose the Stellar Core Saint Physique from the start.
“Look, my Stellarons got MVP! Blue Star people are all freeloaders!” said Li Xinghe, now Lord of the Solar System.
Of course, becoming Lord of the Solar System was only the first step. With his companions, Li Xinghe would go on to conquer the depths of the cosmos.
